JEMMA is a open-source (LGPL) framework which implements the Energy@home specifications for energy monitoring and management application. JEMMA currently supports the ZigBee Home Automation 1.2 and the ZigBee Gateway Device standards resulting from of a collaboration between the Energy@home Association and the ZigBee Alliance.

More information are available on the JEMMA Website and the JEMMA GitHub page.

JEMMA is a modular framework. To better handle development of each module, bundle developments are spread in a number of separate GitHub projects. The following table summarizes the current official JEMMA bundles.

Tutorials, how-tos and other resources are available on the project wiki-based documentation.

JEMMA can also be controlled through REST/WebSocket APIs relying on OSGi Device Abstraction Layer. To start interacting with it you need also these bundles:

• OSGi Device Abstraction Layer
• OSGi Device Abstraction Layer functions
• Energy@Home specific OSGi Device Abstraction Layer functions
• The DAL adapter for JEMMA: it registers DAL services for JEMMA devices
• The DAL web APIs

Take a look at this wiki page to discover functionalities that can be exposed by JEMMA devices
